Honestly speaking the FTTR market on TB is hella confusing, you might end up buying the wrong equipment if you’re not careful

Mainly just need to ensure you get GPON variant but not sure if your OLT will even accept this ONU made for CN market

My personal opinion is just get a switch with SFP+ port and run the fiber with a SFP+ to SC Fiber converter with the super thin fiber.

Router -> Switch (Uplink on 1G/2.5G) / (Downlink to sub switch with 10G over fiber) -> AP or more switch according to your needs
